BRIDLE-BIT.

SPECIFICATION forming part of Letters Patent No. 326,648, datedSeptember 22, 1885.

(No model.)

To all whom t may concern.-

Be it known that I, CHARLEs E. HEINZE, a citizen of the United States,residing in Newark, Essex county, New Jersey, have invented certain newand useful Improvements in Bridle-Bit Mouth-Pieces, fully described andrepresented in the following speciticatiomand the accompanying drawings,forming a part of the same.

rIhis invention consists in a bridle mouth! piece formed of a bundle ofiiexible wires secured in suitable heads, so that the cheeks may beattached thereto, and the wires are shown herein as twisted into a wirerope, so as to secure a greater degree of flexibility, as it is wellknown that a bundle of parallel straight wires or fibers is not easilybent, on account of the extensionupon one side of the bundle and thecompression at the opposite side.

In the annexed drawings,Figure lis alongitudinal section of amouth-piece transverse to the rings, the wire rope not being showninsection, and the ends being shown as soldered into sockets formed in theheads. Fig. 2 isa view of the mouth-piece and rings, with the ends ofthe rope and its sockets shown in section, the manner of fastening therope at each end being described hereinafter.

A is the rope; B, the heads at each end of the rope, into which therings C are fastened in any ordinary manner; and D,D,and D2are socketsattached to the heads for securing the ends of the rope thereto. Threedifferent methods are shown in the drawings for fastening the rope inthe sockets, Fig. l showing parallel sockets D integral with the headsB, and having the ends of the rope secured by solder. In suchconstruction the ends of the rope and the interior of sockets are tinnedin the ordinary manner, and then sweated together by heat, as is common.

In Fig. 2 the sockets are removable or iliade apart from the heads andsecured thereto, a threaded plug, B', being formed upon the side of thehead and fitted to the outer ends of the sockets. The opening at suchouter end is made larger than that at the inner end of the socket, thesocket being thus enlarged internally to permit the expansion orfastening of the rope therein. Such expansion may be effected, as shownin the section at the left end of Fig. 2, by making the socket D'conical internally and driving a tapering pin, E, into the center of therope, or by recessing the socket D2 with ashoulder, F, and riveting orbending the wires at the end of the rope over upon such shoulder, asshown at the right-hand end in Fig. 2.

The rope is distinctly shown in the drawings as formed of separatestrands made of fine wires twisted together, and the ends are thuseasily expanded in the manner described, and when secured in the socketsbecome firmly attached to the heads B, While the intermediate part at Aretains the desired degree of ilexibility. In place of the pin E, meltedmetal may be poured in the central opening of the expanded rope, as isindicated by the dark spot at G,at the right-hand end of Fig.2.

The state of the art in such inventions is indicated in United StatesPatents Nos. 56,87 2, 56,923, and 69,079, the latter showing large wirestwisted together, but in such manner as to form a stiti' mouth,77 asclaimed therein. Vires have also been twisted so as to form hinges orjoints, and thus form a iiexible mouth; but in such cases the strength Isecure is unattainable, as the entire construction is no stronger thanthe separate links. My improvement also differs from these in thefacility with which the ends of the bundle of wires can be secured inthe heads, their ilexibility enabling ine to bend or wedge them in themanner shown above, for securing them in the sockets, and thus removingand renewing them when worn. I

I am also aware that a mouthpiece with cheeks has been made by twistingtwo wires or rods together, andv I do not, therefore, claim the meretwisted wires in my construction, but the rope formed ot' separatestrands which are individually composed of several distinct wires. Itwill therefore be seenthat the dexibility ot' my mouthpiece is dependentupon the use of tine wires and upon their being formed into separatetwisted strands united into a rope, as such construction is much moreflexible than any other. I have, however, claimed my invention as abundle of tine flexible wires to distinguish it from the rigid twistedwires heretofore used, but not combined into strands.

In Fig. l a rubber covering, R, is shown, which Amay be stretched overthe surface of the rope to protect the horses mouth, if' required, fromthe roughness of the rope. Such covering may be used, if desired,although I make no claim to the same, as it has long been used for asimilar purpose.

It is obvious that the sockets D and D7 are removable from the heads B,and in case the strands or wires of the rope A become worn the rope maybe removed from the sockets by unfastening its ends, and a new pievesubsti tut'ed without any change in other parts of the bit.

Having thus described my invention, I claim the mouth formed of the wirerope in the following manner:

I l. ln atlexible mouth-piecefora bridle-bit, the combination, withsuitable end pieces or heads, of the intermediate bundle of fineflexible Wires twisted into strands and united into a exible rope 'andsecured in the heads, substantially as herein described.

2. In a mouthpiece for a bridle-bit, the combination, with Vthe heads B,of the removable sockets having the wire rope fastened therein,substantiall y as shown and described. 3. The combination, with theheads B, provided with the threaded plugs B', of the sockets providedwith an external aperture to t the Wire rope and expanded internallywith the ends of the Wire rope A, expanded within them, and the socketsscrewed to the plugs B, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
